Resumen
Las tendencias del calentamiento global son más altas de lo que se informó anteriormente, sin evidencia de una desaceleración. Las últimas décadas muestran un aumento del calentamiento, desafiando la idea de un calentamiento global "hiatus". Este análisis actualiza los datos globales de temperatura de la superficie.
Área de la Ciencia:
- Ciencias del clima ciencia del clima.
- Análisis de la temperatura global Análisis de la temperatura global
Sus antecedentes:
- Debate en torno al "hiato" del calentamiento global desde 1998.
- Necesidad de un análisis actualizado de la temperatura superficial global.
Objetivo del estudio:
- Para presentar un análisis actualizado de la temperatura superficial global.
- Para reevaluar la tendencia del calentamiento global y la noción de una pausa.
Principales métodos:
- Análisis actualizado de los datos de la temperatura superficial global.
- Comparación con informes anteriores, incluido el Grupo Intergubernamental de Expertos sobre el Cambio Climático (IPCC).
Principales resultados:
- Las tendencias mundiales de la temperatura de la superficie son más altas de lo que se había informado anteriormente.
- La tasa de calentamiento en los primeros 15 años del siglo XXI es comparable a la de la segunda mitad del siglo XX.
- Las últimas décadas muestran un aumento significativo en las tendencias del calentamiento global.
Conclusiones:
- El concepto de una "desaceleración" o "pausa" del calentamiento global no está respaldado por los datos actualizados.
- Se indica un calentamiento global continuo y potencialmente acelerado.

01:50Global Climate Change
29.8K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

01:29Bias in Epidemiological Studies
1.7K
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

01:03Precipitation Gravimetry
16.2K
Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

01:14Temperature Measurement Sites
4.2K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?
